11-1-3: INTERPRETATION:
   A.   Validity Of Other Laws: Where this title imposes a greater restriction upon the use of structures or land or upon bulk of structures, or requires larger open spaces or yards than are imposed by other ordinances, laws, or regulations, the provisions of this title shall govern. However, nothing in this title shall be construed to prevent the enforcement of other ordinances, laws, or regulations which prescribe more restrictive limitations.
   B.   Severability: In case any portion of this title shall be invalid or unconstitutional, as declared by a court of competent jurisdiction, the remainder of the title shall not thereby be invalid, but shall remain in full force and effect. (1991 Code § 16-11-110)
